Answer:

Subtraction.  

Step-by-step explanation:

We have been given an expression: [tex]7x+3x+4=24[/tex].

Simplify our given expression:

[tex](7+3)x+4=24[/tex]

[tex]10x+4=24[/tex]

Subtract 4 from both sides of equation:

[tex]10x+4-4=24-4[/tex]

[tex]10x=20[/tex]

Divide both sides of equation by 10:

[tex]\frac{10x}{10}=\frac{20}{10}[/tex]

[tex]x=2[/tex]

Therefore, the missing reason for the shown argument is subtraction.
